BOWIE, Md., Feb. 29, 2012 (GLOBE NEWSWIRE) -- James W. Cornelsen, President & Chief Executive Officer of Old Line Bancshares, Inc. (Nasdaq:OLBK), the parent company of Old Line Bank, reported that net income available to common stockholders increased $3.9 million to $5.4 million for the twelve months ended December 31, 2011, compared with $1.5 million the prior year. Earnings per basic and diluted common share were $0.86 for the twelve months ended December 31, 2011 and $0.39 and $0.38, respectively, in 2010.

"The acquisition of Maryland Bankcorp, Inc., which we completed on April 1, 2011, was the primary contributor to the increase in net income for the past year, as well as increases in net interest income, non-interest revenue, and non-interest expense. Throughout the year, we have been consistently increasing our underlying operating earnings even as we absorbed the costs associated with integrating the acquired banking company into our infrastructure. We are now the sixth-largest independent commercial bank based in Maryland, with assets over $800 million and 19 full service branches serving five counties," said James W. Cornelsen, President and Chief Executive Officer. "Despite a difficult banking environment, we were able to produce results that demonstrate the quality and potential of our franchise, as well as the strength of excellent market demographics over our expanded footprint. As we enter 2012, we are well positioned to further execute on our goal of becoming the premier community bank in the Washington, D.C. market."

The continued profitability of the company was primarily the result of a $13.5 million increase in net interest income for the year, and a $1.4 million increase in non-interest revenue. The increase in net interest income was predominantly the result of a $13.8 million increase in total interest revenue for the year. The increase in total interest revenue derived primarily from the $240.0 million or 80.00% growth in gross loans that occurred mostly because of the acquisition as well as from organic growth of approximately $50 million. We also received full and partial payments on several acquired non-accrual loans that allowed us to accrete approximately $1.9 million from credit related discounts to interest income during the twelve months ended December 31, 2011. These increases to net income were partially offset by a $9.5 million increase in non-interest expense, a $718,000 increase in the provision for loan losses and a $276,408 increase in interest expense. The increase in non-interest expense was a result of the costs associated with operating a larger branch network and bank franchise.   

For the three month period ended December 31, 2011, net income available to common stockholders was $2.0 million or $0.29 per share, up 15.19% over the $1.7 million or $0.25 per share reported for the linked third quarter ended September 30, 2011. Net income increased primarily because of an approximately $515,000 reduction in non-interest expense and an approximately $540,000 decrease in taxes during the period. The reduction in non-interest expense occurred as a result of our efforts to reduce operating costs and a reduction in merger and integration expenses. As a result of our continued and improved profitability subsequent to the merger, we recorded a one-time reduction in income tax expense during the fourth quarter of 2011.  

A $646,000 decline in net interest income and a $133,000 reduction in non-interest revenue partially offset these improvements. Net interest income declined from that reported in the third quarter primarily because, as we previously reported, during the third quarter we received full and partial payments on several acquired non-accrual loans that allowed us to accrete approximately $1.1 million from credit related discounts to interest income. During the 4^th quarter of 2011, we recorded $395,928 from credit related accretion. Non-interest revenue declined during the third quarter of 2011, primarily because we recorded an approximately $213,000 non-recurring gain on earnings on bank owned life insurance that arose from the loss of a colleague that was offset by a $183,000 expense payable to the estate and recorded in employee benefits. This was partially offset by a $153,830 increase in gains on sales of other real estate owned as we continued to dispose of the other real estate owned that we obtained in the acquisition.

Our asset quality continues to remain strong even with the addition of the acquired loan portfolio. We have not experienced any substantive increase in non-performing assets that we held prior to the acquisition (legacy loans). In accordance with accounting for business combinations, we have recorded the acquired assets and liabilities at their estimated fair value on April 1, 2011, the acquisition date. As part of the fair value process, we were required by current accounting principles to eliminate the allowance for loan and lease losses associated with the acquired loans which caused the allowance for loan losses to decline to 0.69% of total gross loans at December 31, 2011 from 0.82% at December 31, 2010. For the three and twelve month periods ended December 31, 2011, we recorded an $800,000 and a $1.8 million provision for loan losses. Although our legacy loan portfolio's asset quality remained stable, we did experience approximately $50.0 million in organic growth during the twelve month period and $24.2 million during the three month period. There are indications that the economy may be on a path to recovery. However, there are also indications that it may experience either flat or negative growth in the near term and this could negatively impact our borrowers' financial stability. Additionally, until we are able to adequately access the underwriting skills of our new lenders and the impact the acquisition may have on our internal management capabilities, we believe it is prudent to increase the allowance. Based on our history, internal analysis, the ratio of non-performing assets, and the satisfactory historical performance of the loan portfolio, management believes the allowance continues to appropriately reflect the inherent risk of loss in our portfolio and the current economic climate.
